this is a working query but may not be the best one.

List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
since i am trying this too, i figure i ask in this thread...

i am noticing that the %{Calling-Station-Id} variable is not expanding
during execution, and therefore the query against LDAP is failing.  the
query against LDAP when run with ldapsearch does return the value i am
looking for.  not sure if this is self inflicted...
